    Also getting Semaphore.WaitforSignal up near the ~100ms range on Mac, in editor and builds. It is nested under skinnedmeshes.update in my profiler, something I'm not seeing anyone else here report. So not to throw out a red herring, but not necessarily GC related, HDRP related, etc.

    To anyone hitting the Canvas.BuildBatch stall issue - we are working on a fix for it at the moment.

    I too have been having issues with this.
    When building a test to iPhone 6s and using the profiler I saw that I was getting Semaphore.WaitForSignal under the Canvas.BuildBatch which was taken ~ 85ms.

    Then I decided to remove Ui completely from the scene then I noticed I was getting the same Semaphore.WaitForSignal But this time it was under MeshSkinning.Update which is also taken around the same ~85 ms.

    Using Unity 2019.2.9 and running on iPhone 6s as the testing device and the profiles are from the device
    Didn't really know where else to post this issue.
